Why Most People Freeze Glass Wrong (And How to Do It Right!)
Imagine prepping a week’s worth of meals only to find the food spoiled or stale after a few days due to poor storage. Or perhaps you’re tired of having plastic containers warp in the microwave or retain food odors.
Glass storage containers might be the game-changer you didn’t know you needed. With airtight seals, better durability, and a non-toxic profile, these containers ensure that your food remains fresh, safe, and conveniently visible. Let's dive into why glass storage containers are the ideal upgrade for your kitchen.
What is Freezing Glass Containers?
Freezer glass containers refer to the method of storage wherein food items or liquids are contained in glass vessels at below-zero temperatures. This is how one can preserve leftovers from meals or store meal preps with a liquid content, such as soups and sauces.
Not all glass is suitable to be in the freezer, though; some are more capable of withstanding temperature change than others due to the materials used, such as borosilicate or tempered glass containers.
Proper management of factors such as allowing room for expansion and avoiding sudden temperature changes will prevent cracking in the glass, hence convenient to store food for a long period, and it is also eco-friendly.
Top Benefits of Freezing with Glass Containers
Glass containers come with a range of benefits that make them a superior choice for food storage:
-
Keeps Food Fresh:
Glass containers seal tightly, helping avoid moisture loss and prevent freezer burn, which keeps food fresher for longer.
-
Chemical-Free Storing
Unlike some plastics, glass is non-toxic and free from chemicals like BPA, making it a safe choice for long-term food storage.
-
Durable and Reusable
Made to last, glass containers can withstand repeated use, making them a sustainable option that minimizes waste.
-
Easy to Clean
Being non-porous, glass resists stains and odors and is safe for dishwashers.
-
Versatile Use
Glass containers are safe to use in the freezer, microwave, and oven, making them ideal for meal prep and reheating.
-
Eco-Friendly Choice
Glass reduces dependence on single-use plastics and is recyclable, helping to lower environmental impact.
-
Temperature Stability
Glass containers maintain a consistent temperature, keeping frozen foods fresher longer.

Comparing Food Freezing In Glass vs Plastic.
There are certain reasons that make glass a better and a safer choice when it comes to storing food in the freezer. Let us review the comparison table below:
|
Feature |
Glass Food Container |
Plastic Food Container |
|---|---|---|
|
Temperature Resistance |
Can handle extreme cold and hot temperatures but may crack if subjected to sudden temperature changes. |
Generally resistant to temperature changes but may warp or become brittle in the freezer. |
|
Durability |
More durable but prone to breakage if dropped or mishandled. |
Less prone to breaking but can crack over time due to freezing and thawing cycles. |
|
Safety |
Free from chemicals like BPA, making it a safer option for food storage. |
Some plastics may contain chemicals that can leach into food, especially if not BPA-free. |
|
Environmental Impact |
Reusable and recyclable, making it a more eco-friendly option. |
Less eco-friendly due to limited lifespan and potential chemical content. |
|
Weight |
Heavier, which can be a drawback for portability or storage. |
Lightweight and easy to carry, ideal for portable meal storage. |
|
Cost |
Generally more expensive upfront but lasts longer. |
More affordable initially but may need frequent replacement. |
|
Visibility of Contents |
Transparent, allowing easy identification of stored food. |
Available in clear or opaque options, but visibility may be limited. |
|
Seal and Leak Resistance |
Provides a more airtight seal, reducing freezer burn. |
Can provide a decent seal but may be prone to leaks over time. |
Busting the Common Myths about Freezing Glass Containers
Myth 1: All glass shatters in the freezer.
Busted: Tempered and borosilicate glass can handle freezing when used correctly.
Myth 2: Glass containers can be frozen without leaving any space.
Busted: Leave headspace for liquids to expand; overfilling can lead to cracks.
Myth 3: Glass is dangerous for freezing liquids.
Busted: Glass is safe for freezing with the right precautions.
Myth 4: Freezer burn is inevitable with glass containers.
Busted: Proper sealing prevents moisture loss, reducing freezer burn.
Myth 5: Glass containers must be thawed at room temperature.
Busted: Gradual thawing in the fridge prevents breakage.
Key Takeaways
- Glass containers can be safely frozen if temperature changes are carefully managed.
- Opt for borosilicate glass for better resistance to temperature shifts.
- Leave room for food expansion to avoid cracks.
- Cool hot foods before freezing to prevent breakage.
- Airtight lids maintain freshness and help prevent freezer burn.
Q: Can you put glass in the freezer?
Yes, you can put glass in the freezer if you follow specific precautions. Use borosilicate or tempered glass containers to handle temperature changes better. Always leave space for liquids to expand, and let hot food cool before freezing. This prevents cracks and ensures safe storage of food without freezer burn. Properly sealed glass containers keep food fresh longer.
Q: Is it okay to put hot glass directly into the freezer?
A: No, hot glass must cool first; otherwise, sudden changes may cause it to crack.
Q: What types of glass are best for freezing?
A: Borosilicate glass is ideal, with high resistance to temperature changes.
Q: How can I prevent glass containers from breaking in the freezer?
A: Leave room for expansion and avoid sudden temperature shifts.
Q: Can I freeze liquids in glass?
A: Yes, but leave extra space for expansion to avoid pressure-related cracks.
Q: Is there a risk of freezer burn with glass containers?
A: Glass containers with tight-fitting lids help prevent freezer burn by keeping out moisture.
